[填空题]Till 2004 how long has he been dead

[单项选择]It is 2 a. m. You took too long over dinner, the coast is still a couple of hundred kilometers away and it is essential to get that early morning ferry. And your car radiator pipe bas split. At times like that, the documents making up your insurance kit lying in the front of your car seem useless. The nearest phone was passed three kilometers back, and it would be reasonable to expect some delay in getting breakdown assistance when you have finally phoned through.
If on the other hand, you’ve got a spare in the car, five minutes’ work should see you on your way again. The majority of breakdowns do involve minor and easily changed parts. A few basic tools and the right mix of spares are well worth the space they take up. But to sort out which ones are most likely to be needed, and to buy them, can be expensive.
That is why the motoring organizations have come up with rental kits. For about 50 pence a day (slightly more to non-members) they will supply a boxed range of spares f

[单项选择]

In the angry debate over how much of IQ comes from the genes that children inherit from parents and how much comes from experiences, one little fact gets overlooked: no one has identified any genes (other than those that cause retardation) that affect intelligence. So researchers led by Robert Plomin of London’s Institute of Psychiatry decided to look for some:
Plomin’s colleagues drew blood from two groups of 51 children each. They are all White living in six counties around Cleveland. In one group, the average IQ is 136. In the other group, the average IQ is 103. Isolating the blood cells, the researchers then examined each child’s chromosome 6 (One of the 23 human chromosomes). Of the 37 land marks on chromosome 6that the researchers looked for, one jumped out: a form of gene called IGF2R occurred in twice as many children in high IQ group as in the average grouw-32 percent versus 16 percent. The study concludes that it is this form of the IGF2R gene,
A. is IQ gene
B. has nothing to do with IQ gene
C. stimulates nerves to grow
D. is decisive to the development of intelligence
